This. invention relates to multiplying and type-writing machines; and it consists of the novel construction, .combination, association, and arran ementof elements and the novel erative notions-thereof, all of which are s own in the drawings and herein'described and claimed;

The obipct of my invention is to produce a aving registering devices wherein numbers may be registered by striking them on a suitable keyboard, in combination with multiplying devices for operating the register to multiply the number therein any desired number of times, (up to the capacity of the machine,) to provide key-controlled mechanism for governing the multiplying devices so that all parts are directly under control of the o erator, to provide printing mechanism so t at the product may be recorded, and to rovide independently operative typewrit- Ing mechanism to meet other requirements,

which are well understood, all of said devices being embodied in a single integral'macm'ne. Figure 1 is a plan view of my machine.

Figs. 24 and 25 Show the 6" and 5 plates, respectively. Figs. 26 and 27 show the construction of the 4 and Figs. 28 and 29 show the construction of the 2 and 1 plates, respectivel Fig. 30 is a sectional view taken on the ine h h of Fig. 20, showing stop device used to stop forward movement of the sectors when any digit iscarriedthereto in multiplying.

Briefly stated, a number is multiplied on this machine by Striking the multiplicand on a set of keys which-register the number in a register. After the number has been registered the multiplier-number is struck on a loop of keys, which by suitable interme iate operative devices will cooperate with the register, thereby multiplying the number Fig. 23 shows one of.

contained therein, producing instead a result ing department to record thereon, so that words, signs, and symbols may be recorded on the same Sheet of paper in any desired relation to the mathematical or arithmetical records.

The base 1 upholds the frame 2, in which are arranged the type-bars 3 belonging to the typewriter-department. The keys and keylevers 4 have suitable lever connections with the type-bars 3 and are arran ed to strike at a common point on the p aten 5. Said platen is provided with the usual attachments for rotation and with an escapement 6 reg 1o ment.

of "known construction, controlled by thet to the multiplying department and are rouped, preferably, near the right of the ke board and are used to strike the multip icand into the register, Figs. 1 and 3. Said levers are pivoted at 12 and extend rearwardly, and their extremities are in a parallel line longitudinally in the machine and are provided with small flat surfaces, upon each of which rests a vertically-movable rod 13, Figs. 2 and 19, said rods being in openings 2 5 in retaining-supports 14. The rods 13 are in a longitudinal row and underlie a transversely-movable carriage 15, said carriage constituting a register, mounted, by means of rollers 16, upon the two track members 17.

o Said carriage-register is actuated leftward relative to the operator by a motor 18, and its movement is controlled by a rack 19, attached thereto and meshed with a gear 20 upon the shaft 21, Figs. 5 and 19, rotation of 3 5 'the shaft being controlled by an escapement 22 of any preferred known construction. The escapement-bar 23 is attached to a rockshaft 24, Figs. 3 and 4,'and is raised and lowered with the rear ends of the key-levers 4o 11, thereby permitting the shaft to turn and the register-carriage 15 to be drawn one step leftward each time a key is operated. The device for raising the bar 23 consists of the rod 25, connected thereto and overlying the key-levers, the opposite end of the rod being when the register-carriage moves.

supported by an arm on the shaft 24. A gear-wheel 26 is on the shaft 21 below the escapement and meshes with the sliding rack 27 and operates the latter in its supports The multiplier spacing-key 28 extends under the rod 25 and also controls the escapement 22 to permit leftward travel of the register-carriage, the purpose of which will be properly 5 5 explained.

A rod29 is suitably mounted in bearings and has a slot 30 in its rear end throu h which a pin extends, connecting said 1'O( loosely with the front end of the rack 27, so that said rack may travel forward Without moving the rod, which is actuated forwardly by a spring 31. To restore the register-carriage to idle position to correct any error made in strikin the number on thekeys, the rod 29 is pushe back, which operation, through the medium the plate. represents.

of the rack 27, turns the shaft 21 and thereby restores the parts.

The register-carriage 15 comprises a series of plates 32, between which are the curved strips 33, Fig. 7, having notches in their upper and lower edges in which the pins 34 reside and which are held in proper position by springs or other suitable devices. The row of pins 34 at the left relative to the operator is over the rods 13 when in idle position,

one pin being provided in each row for each of the ten rods. The operation of a key, therefore, will first raise one of the pins and then release the escapement 22, so that the carriage 15 will be drawn leftward one step to bring the next row of pins over the rods 13. This operation is repeated until the required number of pins have been pushed up. vv hen the carriage is drawn back by operation of the rod 29 or otherwise, the pins are restored to idle position by being drawn under the member 35, which has its left under corner inclined, and forces the pins down. The pins 34 are arranged in rows, with ten pins in each row, the rearward pin of each row representing 0, the next pin 1, and so on, so that any one of the ten digits can be registered in each row.

After the number has been registered in the registercarriage the next operation is to strike the multiplier-number on the keys provided therefor. The multiplier-keys 36 are preferably arranged near the opposite side of the machine from the keys 11, with the multiplier spacing-key 28 separating the two groups. Including the said key 28 there are ten of these keys, one for each of the digits. The levers of the keys 36 are pivoted at 37. The rear end of each of said levers underlies a horizontal projection 38, Figs. 3 and 19, rigid with a vertically-movable member 39, properly guided by the slots 40, inclosing a rod 41. It follows that operation of either of the keys 36 will raise a distinct member 39 belonging thereto. The upper end of each of the members 39 carries a horizontal extension 42,

which operate in slots formed in the side or frame plates 43. 1

Mounted longitudinally near the upper rear end of the machine isv a series of groups Aof multiplying devices in the form of plates. There are nine plates in each group, one plate for each digit, not including the 0. The plates of each digit are identical in construction throughout the different groups; but the plates of the different digits have distinctive constructions. These plates are related to the register-carriage 15 in such manner that each plate may be moved to register the product of a digit in the number registered in the carriage 15 multiplied by the digit which The opposite edges of the plates are formed to register the digits of the product, the tens of the product being indicated on one edge and the units of the product on the opposite edge of the same plate. In the problem herein followed it will be shown that while each plate constitutes a complete register for the roduct of a digit of the multiplicand multip 'ed by the digit of the multiplier-number for which the late stands, yet the tens and units are carrie forward and registered in their respective orders in a set of re 'ster andtotal wheels, from which the fina product may be recorded and the machine cleared forfurther use by the same operation. v

The plate'forl the digit F 9 is designated by a,for8 by b, for 7 by c, for 6 by d, for "5 by e, for 4; byf, for 3 by g, for 2 by h, and for 1 by i. In the arrangement shown-the (9 plate is at the right of each group relative to the operator, and the other plates are in consecutive order down to 1 atthe left. The arrangement of the plates in the groups is immaterial so long as each digit is represented by a plate. Referring now to the relation between these digit or multiplying plates and the keys 36 through the medium of the members 39 and the horizontal extensions 42, attention is directed to Figs. 18, 19, and 20. The parts 42 extend across the rear ends of'all the plates a b c, &c. The rear ends of the corresponding. digit-plates in the difi'erent series are identical, and each is provided with a series of shoulders 43*, Fig. 18 and Figs. 21 to 2-9, inclusive. The rearmost member 39 is connectedto the 9 key, and said member car ries the uppermost extension 42. The extension 42 belonging to the 9 key rests directly under and against all the shoulders 43 except those on the plates 0 representing the digit 9. As shown in Figs. 18 and 21, the shoulder on the plate a of the series indicating the digit 9 is above the shoulders on the other plates of the series. Therefore when the 9 key is operated all the series except the plate a in each series will be lifted up by the extension 42 controlled by said 9 key. Likewise all the plates in all the series of groups will be uplifted by the 8 key-controlled member 42 except the plates 1) denoting 8, and so on throughthe series of keys and plates, each key on operation moving all the plates except the plates corresponding to the digit of the key operated.

All the plates a b c, &c., are held vertically in suitable frames and have arms 44, Figs. 21 to 29, inclusive, which extend through and operate in slots in the cross member 45, and hence are properly guided. A series of bars 46 is mounted in suitable supports and are movable longitudinally in the machine. Said bars are just at the leftof the idle position of the register-carriage 15, and the relative arrangement is such that the first stepof the carriage leftward moves the first row of pins 34 under the first bar, and the next step carries a row to the next bar, and so on. Shoulfront to 9 on each bar, so that the movepins. Types 48, hi .4,

ment of the bars as determined by the register-pins 34 will locate the COITBSPOIIQIDg type under the platen in position to be driven against the paper. The rear end of each bar carriesa projecting arm 49, higs. 19 and 21, there being one bar for each group A of multiplying-plates, so thatthere is also one arm Each of the arms 49 carries a for each grou a horizontal pm 50, 1 igs. 18 and 21, the length of each pin being sufiicient to extend entirely under a group of plates. Notchos 51 are formed in the lower sides of the multiplyingplatcs, -and said notches inclose the pins 50, thereby forming connection between the platesa b c, &c., and the bars 46, one bar controlling an entire group of plates. When any key 36 is operated, all the plates will be raised and released -from the pins 50 except one plate in each group A, the plates not so released being the plates representing the digit of the key operated. "Therefore when the bars 46 are moved forward, as hereinafter set out, each bar which moves will carry with it" one plate of the corresponding. group of lates. After-the multiphcand-number has een registered in the register-carriage as described the first digit at the right of the multiplier-number is struck on its proper key, which, through the member 39, releases all the plates a b c, &c. except one in each group. Then the rack-bars 46, for which pins 34 had been positioned, are moved as now to be described, and such movement operates the plates still in connection therewith.

All operating-handle 52 is conveniently mounted and-by a link 53 connects with a IIO lever 54, rigid on a shaft 55, so that forward operation of the handle will rotate the shaft.

Another lever 56, Figs. 4 and 19, is rigid on are two camlevers 60, so that forward operation of-said handle 52 also rotates the shaft 59, and thereby moves'the cam-levers into the slot formedby the arm 61 on the cor-.

responding cam-lever 60, so tgat the latter will move the levers 62 when operated. A spring-actuated plate 64 is pivotally supportedin the carriage 15 and in idle position is Two levers 62 are
